Communications Infrastructure No Match for Katrina
jfourier writes "In this age of cheap commoditized consumer electronics and advanced mobile technology, why can't all the people of a city make contact during an emergency? Cell phone circuits filled up during 9/11 attacks and in the wake of hurricane Katrina very few victims can make contact with their families, despite the fact that they have all those mobile phones. The Red Cross is looking to deploy satellite equipment to restore communications in affected areas." From the article: "Katrina made landfall in Louisiana early this morning with sustained winds of 145 mph, but veered just enough to the east to spare New Orleans a direct blow. Even so, flooding, power outages and heavy damage to structures were reported throughout the region.
The Red Cross tomorrow expects to begin deploying a host of systems it will need, including satellite telephones, portable satellite dishes, specially equipped communications trucks, high- and low-band radio systems, and generator-powered wireless computer networks, said Jason Wiltrout, a Red Cross network engineer.

Do I even need to say it?
Ever since the midwest blackout I've been meaning to get an operator's license... for 2m if nothing else.

Beat out messages on drums!
Of course the system failed. The cities have flooded, there is no power in much of the area, and a good number of towers and other infrastructure has been damaged.
The winds reached 140+ miles per hour. The uplands received 5+ inches of rain in 24 hours.
"Rocky Rococo, at your cervix!"
Let me point out that this is one of those times when battery operated amateur radio provides one of the best ways to get messages in and out of an affected area. In fact, this story at the ARRL has some information on how hams are helping in the recovery effort.
I remember a story some time ago about a plan to deploy blimps for cell and wi-fi service. I wonder if that plan might be viable now? They could fly away for the storm then fly back shortly afterwards.
WTF do people expect? Millions of people displaced and each having at least one relative and likely several in other parts of the world trying to reach them. This is to be expected. Why should a network outage and phone difficulties be news in such a catastrophy?

who's evacuated out of state and has a cell phone with long distance service, but people are having problems calling TO him. Presumably because the call is still trying to get to New Orleans to figure out where to forward his phone call.
Technology can certainly help us in times of need. The Mayor of New Orleans was able to order an evacuation, through the great telecommunication and media infrastructures that we have, people were able to be warned, which probably saved thousands of lives. I say this, because when natural disasters like this hit third world countries, there are many, many, many more deaths. So our communications infrastructure and other technologies DO HELP. Of course, we have had television and radio and the like for a while, an evacuation and warning like this would have been possible probably even 40 years ago. This catagory of technology would also include things like interstate highways, helicopters, boats, and the like, which help rescue operations get where they are needed. Another development we have that helps is a highly organized and functional government. George Bush can immediately grant disaster funding to these states and the rescue operations get moving. Without government direction and organization, it would take whatever volunteer goodwill organizations that go down there a lot longer to coordinate their efforts, and would be much less effective. It is true that the cell phones stop working when the power is cut to the tower, but the same is true for regular phones. But, the amazing thing is, to restore phone service we can fly a couple satellites, which is a lot easier than waiting for the water to recede and rebuild all the phone lines. So technology is helping in this case as well. A disaster like this does show us how powerful nature is, and that sometimes there is nothing we can do to stop a disaster, but we can do our best to minimize the tragedy.
It seems like Verizon, Sprint or someone could make a boatload of money from opportunities like this. They could have a few mobile cell towers that run from generators. When a tornado, hurricane, wind storms, or whatever hit, they truck those towers in as temporary replacements. The local government will appreciate it. The local cell phone users will appreciate it. The people not on their plan will make them a bundle in roaming fees!
They could store them centrally inthe country. Since they usually have a large warning, they could get them nearby the pending storm. Right after the storm clears, instant tower.

The networks are not designed for theoretical maximum capacity, they are designed for average peak observed capacity. If there are 1 million cell phones in use and only 10-20% of them are actively transmitting at a time during normal use, why shell out for 5 times as much infrastructure as is needed to support that level of use? A catastrophe like Katrina or 9/11 only happens once every few years; the rest of the time the excess capacity would only be draining resources - not just from the corporate bottom line, but from maintaining the 10-20% of the equipment that's actually used by subscribers.
Wind no, rain yes.
Ku Band singals are in the microwave range of EM frequencies, so are vulnerable to rain fade (which is ironic since many Meteorologists get their data this way).
C-Band isn't as bad.
Wind does not affect satellite signals. It effects the dishes. Rain does attenuate the signal however. Regardless, the storm will have blown over by the time the Red Cross gets the equipment setup. All and all this was not a well thought out post: 1. Capacity : Yes, the cell companies could build out the capacity to support everyone calling at once but you don't want to foot the bill. Every once in a while you need to speed to pass some one, you don't buy a porsche do you? Why? Because most of us justify it, much less afford it. 2. Robustness : Lets see if you house stands up to 20 feet of water and 145 mph winds. I'm certain it won't... why not... because you don't want to pay for it. Cell phones are not a public service, they are a commodity and are priced and scaled accordingly. I'm sure the cell phone companies would be more than happy to accomodate you if you'll sign the 10 year $250/month service contract.
Big shot. It is 6200x8000 pixels and 8.4 MB big. Amazing how clear and big we can get with today's satellites.

Well maybe the French weren't that stupid after all: they did manage to relocate while unloading Louisiana onto the US...
Instead of trying to retain full voice, wouldn't it be better to just limit none essential mobiles to text? Then the system could survive on far fewer base stations, but retain some communications for all. You can surely get many more text messages through the network than voice.
